Conflicts between farmers and herders are a persistent challenge in Sudanian and Sudano-Guinean zones of Benin, largely driven by competition over access to pastoral resources. This study aimed to characterize the prevalence, causes, and typology of such conflicts and to assess their implications for the sedentarization of cattle farming systems. Data were collected from 480 livestock farms across four municipalities (Materi and Gogounou in the Sudanian zone; Tchaourou and Djougou in the Sudano-Guinean zone) through surveys, mapping, and herd productivity assessments. Multiple Correspondence Factorial Analysis was used to classify the conflict types. The results revealed that 52.29% of herders had experienced conflicts, with a higher incidence in the Sudano-Guinean zone (36.88%). Four main categories of conflict were identified: (i) blows and injuries to people and animals (38.64%), (ii) displacement of herders and their farms (34.26%), (iii) property damage and animal slaughter (15.13%), and (iv) violent verbal altercations and animal poisoning (11.97%). These findings indicate that recurrent conflicts are accelerating the shift from transhumance towards sedentarization, underscoring the need for tailored conflict management strategies and sustainable livestock policies.
